The Danvest Power Box® + Solar system is a hybrid power plant for continuous and automated off-grid energy supply. Danvest's unique low-load and fast response capability enables high solar penetration. Direct fuel savings are 30 to 40% per year.*

The - Danvest Power Box® - contains a conventional fixed speed diesel generator fitted with the unique Danvest system. Solar systems simply connect and the system is ready to save fuel.

Unique 'Low-load' operation

A Danvest fitted diesel genset is able to smoothly operate all the way down to zero load and low fuel consumption. When solar energy surpluses, the genset reverses operation - the alternator draws the engine - and diesel consumption will be near zero. When the surplus is stable, the engine can even de-clutch from the alternator to fully stop while the spinning alternator remains connected to the busbar. At all times the genset is able to respond fast on any solar drop or demand increase thanks to the dynamically ensured intrinsic spinning reserve.

The Danvest dumpload controller assists the genset during fast load variations and during low-load operation.

High solar penetration

Up to 100% solar penetration at peak load can be achieved as Danvest fitted gensets can flexibly operate between zero and full load and as Danvest can handle large solar power capacities. High averages of "direct" fuel savings will result in low LCOE.

Robust microgrid

The Danvest system is based on conventional CAT or Cummins gensets and solar systems of all major brands can be added. Continuous performance and a high power quality is ensured by the robustness of the grid-forming low-load diesel system.**

Using solar energy directly

Operating 24/7

Danvest is the green alternative for conventional diesel generators at off-grid and weak-grid locations. The reliable diesel-based hybrid power plant is easy to install, easy to operate and easy to maintain. Danvest can be operated by any local diesel operator. The solar system runs on a service contract.

* These fuel savings increase when demand is mainly during the day** Energy storage systems can optionally be added to also generate "indirect" fuel savings. Danvest provides a stable charging load and saves on cycles as the storage system does not need to be used for load balancing.
